Culturas de escola e excelência: entre a integração de todos e a distinção dos melhores
2018
Sem perder de vista a multidimensionalidade inerente aos percursos escolares, este texto procura refletir sobre a importância dos fatores organizacionais na construção dos resultados académicos. O enfoque incide sobre as dimensões intra-escolares, designadamente os efeitos da cultura de escola (nas suas diferentes facetas) e dos processos de liderança sobre a socialização dos estudantes. Optando por uma linha de pesquisa reflexiva, procura-se compreender os processos de construção de habitus (no sentido de Bourdieu) e os sistemas de disposições (na ótica de Lahire) estruturadores da cultura organizacional de escola. Do ponto de vista metodológico recorre-se a dados recolhidos no âmbito de u…

Bloque detector PET basado en cristales monolíticos y fotomultiplicadores de silicio
2017
La tomografía por emisión de positrones (PET) es una técnica de imagen médica, encuadrada en la medicina nuclear, consistente en la generación de imágenes a partir de la detección de radiación gamma resultante de la aniquilación de positrones, emitidos por un radiotrazador, con los electrones de tejidos circundantes. Las imágenes PET son de tipo funcional, lo que permite la observación y estudio de procesos fisiológicos, sin embargo, se ha probado que la integración de estos escáneres con otros sistemas de imagen médica que proporcionen imágenes de carácter anatómico mejora notablemente las prestaciones clínicas de ambos equipos. Este tipo de equipos multimodales se conocen como sistemas hí…
Feasibility of a Responsibility-Based Leadership Training Program for Novice Physical Activity Instructors
2021
Most coaches and instructors would like to teach more than just sport skills to their athletes and children. However, to promote athletes' or children's holistic development and teach them to take responsibility and lead, requires the coaches and instructors to first master the skills themselves. Therefore, feasible, high quality leadership training programs where coaches and physical activity instructors are taught to teach and share leadership are needed. The aim of the current study was to evaluate the feasibility of a leadership training program to optimize it and to determine whether to proceed with its evaluation. In the leadership training program, eight Finnish novice physical activ…
Shared Leadership Regulates Operational Team Performance in the Presence of Extreme Decisional Consensus/Conflict: Evidences from Business Process Re…
2019
This study focuses on decision-making within operational teams. Grounding our argumentation on group decision-making literature, we argue that adverse behavior patterns may affect the way in which consensus is achieved within the team, and that team performance has an inverted U-shaped relationship with the level of consensus. Then, by relying on leadership literature, we pose the hypothesis that the level of shared leadership inside the group moderates this U-shaped relationship. To empirically test our literature-based argumentation, we use longitudinal data collected in the years 2014 and 2015 from business process reengineering projects, each lasting three months, conducted by 141 maste…
Appetite for destruction: A psychometric examination and prevalence estimation of destructive leadership in Sweden
2021
There is a growing awareness that destructive leadership has a significant negative impact on employe outcomes. However, little is known about the content and dimensionality of this multidimensional concept, and there are few reliable measures available for organizations and researchers to evaluate these behaviors. Based on a representative sample (N = 1132) of the Swedish workforce, the aim of this study is threefold: first, to examine the factor structure and validity of an easy-to-use multidimensional destructive leadership measure (Destrudo-L)in the general Swedish work context; second, to identify destructive leadership profiles using latent profile analysis (LPA), and determine in wha…
Experimental and robust modeling approach for lead(II) uptake by alginate gel beads: influence of the ionic strength and medium composition.
2014
Abstract Systematic kinetic and equilibrium studies on the lead ions removal ability by Ca-alginate gel beads have been performed by varying several internal parameters, namely, number of gel beads, nature and composition of the ionic medium and pH, which allowed us to model a wastewater in order to closely reproduce the composition of a real sample. Moreover, the effects brought about the different ionic species present in the reacting medium have been evaluated. Differential Pulse Anodic Stripping Voltammetry (DP-ASV), has been systematically used to perform kinetic and equilibrium measurements over continuous time in a wide range of concentration. Kinetic and equilibrium data have been q…
Applying RUG-III for reimbursement of nursing facility care
2006
The Resource Utilization Groups (RUG-III) case-mix classification is becoming an internationally accepted methodology for determining payment for nursing facility and care. In this paper we discuss the key concepts of case-mix reimbursement and several different payment approaches based on RUG-III. In discussing the empirical evidence of case-mix reimbursement, we draw especially on the US experience. Clearly, the success of case-mix reimbursement depends not only on the payment design, but also on the ability to foresee market conditions and the regulatory environment in which the payment system is being implemented. Moreover, we demonstrate the need to develop a case-mix based reimburseme…
Ethical Dilemmas in Finnish Debt Collection – An Explorative Case Study
2016
It is inevitable that ethical questions arise in debt collection organizations and leadership, which is then good ground to identify whether debt collection is good or evil. Therefore we consider that a good standpoint for qualitatively explain the ethical dilemmas arising in our case study context. The article adopts a case study approach to examine Finnish Collection Agency Ltd., and applies a qualitative content analysis of interview data gathered by asking five employees to answer ten questions about how they see conflicts between their work and their own ethical thoughts. We obtained a rich description of the issues facing the debt collection business in Finland. In addition, the conce…
